Can anybody please provide some detailed sources on FWHT. I have tried to google but couldn't find any. I have read CS academy's tutorail but it largely covers its Implementation rather inner workings and this blog which extensively explains XOR convolution but lacks generalization details of the concept. Thanks :)
This seems to be a rare and interesting topic, would like to see some good sources.
This article really helped me on how to obtain transformation matrices for different kinds of convolutions.
That article helped a lot in generalizing the idea. Thanks :)
